Most people don't know the specifics of the project history and are under the assumption that we've been developing this game for 10 years with a full team working full time.
In reality, there was a single guy ( me ) working 6 years out of these 10 alone, part time, mostly just on the tech. That already puts things into perspective. So, no, we haven't got 8-10 guys working on this for a decade.
During the past 4 years, we had to do major engine upgrades in order to not lag behind in terms of tech ( physical-based lighting was one of the major steps ), which required to change the entire workflow / pipeline. Artists had to relearn everything. And again, nobody's working full time, so you don't figure that stuff out in just 2-3 months.
It is true that it took us a lot of time to get this Kickstarter shipped out of the door. But you have to explain to people how to put things into perspective. Star citizen worked a year on their KS before it launched. They had a small team of professionals, working full time, plus subcontractors. The development costs of the SC KS was probably in the 500K-1M$ alone. Just for the KS.
With an already existing 3D engine (Cryengine).
Not only have we worked part time, but we also had to develop and mature all the tech.
There's a limited amount of progress we can do working that way. Which is exactly why we're going to KS to get funding, to allow us to work on this full time and to develop the game within 2 years.
Think about it in terms of man-hours instead of total time and you'll see that in comparison to SC, E:D or other games, we are no less productive. We just do our best with the amount of time we have.
Not only is this not true, since we were in development well before either went public; but also keep in mind we're not playing in the same category.
I cannot stress that enough. Now I know people will naturally compare us to KS or E:D because that's what exists.. but really, we aren't going to be a AAA title ( E:D might not be AAA, but it still has a massive budget compared to us. We're probably going to end up with 5 to 10% of their entire budget.. ). You should compare us to other small indy games, like the ones released on Steam ! We aren't going to sell Battlescape at $60, and there's not going to be tons of content. Unless we reach the million dollars or more, of course. We're not trying to become the new Star Citizen or Elite.
